Do this simple test and you will look at ACR and the 50D quite
differently. Take a raw file shot at ISO 12800 and convert it with
ACR (no adjustments) and then use the Canon utility to convert the
file (just make sure you turn off the noise reduction in the Canon
preferences). The Canon software will give you an astonishingly
cleaner image than the Adobe ACR. I was shocked by the difference.
The 50D is excellent!

Really?

At ISO 12800 the DPP noise structure is tighter/finer than ACR with both set at ZERO NR and ZERO Sharpening, but the Noise is not much different here. ACR does some kind of Luma NR and Hotpixel removal behind scenes out of user control, so it will appear more "blobish".

Sure you really have NR off in DPP? The [ NR/Lens/ALO ] Tab shows 0 and 0 and the [Apply] button is grayed out?
